it is time for强调的是：是时候做某事了,重在事情,后面要跟名词(n.)或者动名词（也就是动词+ing=v.-ing）
it is time to强调的是：是时候做...了,重在动作,后面跟动词（原型v.）或动词短语

It is time to do something和It is time for something意思没有区别，但结构不一样。
It is time后面可以用三种不同的句型：
It is time for加名词，如：
It is time for school.
It's time for lunch.
It is time后面加动词不定式，如：
It's time for you to go to school.
It's time to have lunch.
It is time后面可以用从属连接词that引导一个从句，从句中用的是虚拟语气，也就是说从句的谓语动词要用过去式，be动词要用were，例如：
It is time that you went to school.
It is time that I had lunch.
It is time that the naughty kid were taught how to put in good order everything that belongs to him in his room.本回答被网友采纳
